A system is disclosed for supporting a rotary load on a cushion of gas that is developed in a gas-bearing structure. Both radial and thrust loads are carried in the system as disclosed, and similar principles are utilized in the operation of each such component structure. A closure member cooperates with a load member, carrying a rotary load, to define the space in which a gas cushion is developed. To preserve the space relationship between the load member and the closure member within operating limits, the two structures are position servo-controlled. As disclosed herein, signals are developed that are indicative of the relationship between the members thereby defining the chamber in which the gas cushion is provided. A servo-control structure receives those signals to control the flow of gas for preserving the desired positional relationship by applying impact or impinging gas forces. As disclosed, a plurality of opposing ports are provided to discharge gas, and thereby exert impact forces to preserve the bearing elements within operative relative positions.
